So Mission Models paints are being hailed as the saviour of acrylic paints there is plenty of blather out there on the internet so go look it up for yourself. The long and short is a very high pigment count and a very small pigment size; good coverage and improvement spraying behaviour, including reduced overspray. Also the Polyurethane additive for the paints basically triggers the bonding of the paint particles when it dries on the model on not in the bottle beforehand so you you should get a superior smooth and self levelling finish.
Currently the paints are all for Military modellers though aircraft and even SciFi have been mooted. I was interested in the primer anyway as though I use Halford Grey Primer and more often Alclad Grey microfiller I'm still get a rough surface with the later despite lowering my air pressure and trying to avoid overspray.
MM paints are not cheap and been sold on their quality. The Grey Primer, at £7.50 for a small bottle 1oz/29ml, though the thinners at £6.50 for 2oz/58ml is harder to stomach especially as they suggest you use it the also clean your airbrush - fat chance mate IPA will shift the MM primer with no problem, though I will say you can get most of it our with water as it does seem to have longer working time than other acrylics. So I've used it as recommend, 25% thinner to 75% Primer, the thinner necessary to activate the primer. It covers well, red plastic was gone in 3 light coats, forms a very level finish. It it not quite as smooth as I had hoped for especially of you are going for a gloss finish on top. I light rub with 3500 grit micromesh will do the job.
Now the main down side I've found is that this is still acrylic paint and I've come from using lacquer primers which properly bite into the plastic. This raised it head when in the normal course of things I found and area that needed sanding back and refilling. Though you can polish this paint without too much trouble if you use normal sanding sponge/paper it will tear the paint. If you do I have found that if you use micro mesh or other > 1000 grit medium you can feather the edges of the primer and spray without the edges of the paint becoming noticeable. Therefore claims it can be sanded I think are stretching the truth.
Here I sanded back some remedial filling and the re-polished the whole area.
I've now got some white (Mr Color) down on the necessary areas including the nose where a larger white decal goes. On seeing other builds it was evident that the white background to the decal was not dense enough to hide and red/black demarcation and so I will use a scan of the decal to form a masking template for this area. One issue of my own making was I had used red marker pen during construction, despite wiping this away with IPA some had got transferred to the airscoop. It has the amazing ability to leach through multiple layers of paint. That's the plastic you can see where I've rubbed and polished back.
